Audio File Library

The Audio File Library is a C-based library for reading and writing
audio files in many common formats.

The Audio File Library provides a uniform API which abstracts away
details of file formats and data formats. The same calls for opening
a file, accessing and manipulating audio metadata (e.g. sample rate,
sample format, textual information, MIDI parameters), and reading and
writing sample data will work with any supported audio file format. The
Audio File Library lets you work with audio data in whatever format is
most convenient for you.
